Distribution of high-dimensional entanglement via an intra-city free-space link
Fabian Steinlechner, Sebastian Ecker, Matthias Fink +5
Quantum entanglement is a fundamental resource in quantum information processing and its distribution between distant parties is a key challenge in quantum communications. Increasi…
Super-Activation of Quantum Steering
Marco Túlio Quintino, Marcus Huber, Nicolas Brunner
We consider Einstein-Podolsky-Rosen steering in the regime where the parties can perform collective measurements on many copies of a given shared entangled state. We derive a simpl…
Genuine-multipartite entanglement criteria based on positive maps
Fabien Clivaz, Marcus Huber, Ludovico Lami +1
Positive maps applied to a subsystem of a bipartite quantum state constitute a central tool in characterising entanglement. In the multipartite case, however, the direct applicatio…
Autonomous quantum clocks: does thermodynamics limit our ability to measure time?
Paul Erker, Mark T. Mitchison, Ralph Silva +3
Time remains one of the least well understood concepts in physics, most notably in quantum mechanics. A central goal is to find the fundamental limits of measuring time. One of the…
Quantification of multidimensional entanglement stored in a crystal
Alexey Tiranov, Sébastien Designolle, Emmanuel Zambrini Cruzeiro +5
The use of multidimensional entanglement opens new perspectives for quantum information processing. However, an important challenge in practice is to certify and characterize multi…
Passivity and practical work extraction using Gaussian operations
Eric G. Brown, Nicolai Friis, Marcus Huber
Quantum states that can yield work in a cyclical Hamiltonian process form one of the primary resources in the context of quantum thermodynamics. Conversely, states whose average en…
